The hit jobs keep coming: first air pollution is associated with eye problems, such as macular degeneration. Then air pollution is linked to infant mortality. Next, in more polluted counties in the US, there are more neurological disorders, and that ends up in bipolar and depressive disorders. Finally "ambient air pollution has a substantial impact on hospital admissions" and even death: in India last year, air pollution was responsible for 1.2 million deaths in India.
The evidence is accumulating that the toll of air pollution is much higher than previously imagined. If only international institutions- wait, heck, even if the US- was interested in fighting pollution....
Update November 2019: A libertarian blog has posted this long run-down on the effects of air pollution. Given that these folks are not usually quick to talk about social problems (other than over-regulation!) it surprises me to see them being so open about this.
